Im doing a 4.3 with manual trans to a 6.0 engine out of an escalade that was automatic, what can i do about the wire harness to be able to connect it to my manual trans???? Another question everythings hooked up to the engin other than the trans wires on the wire harness, the engine starts and then shuts off after about 2-3 seconds. Could this problem be vats??? Im using the stock pcm that came with that engine???
